Help me understanding some new lenses

[John Smith]

Hello,

First post here so be kind J I am confused about some modern lenses compared to some 5 years Essilor lenses. The new lenses (2 pairs) one non branded and another from Essilor (with Crizal forte) have an anti reflex protection that almost any reflex tends to be green and some brighter then the old´s Essilor witch most reflex tend to be a mix of writhe and green.

I prefer the old lenses because although they seem a little less transparent the anti reflex protection is better. I wonder if this is caused because of the Crizal forte protection witch according to Essilor from the 3 protections pack that they have that is the best but also the one that takes more layers and so the reflex is brighter.

All lenses are made of polycarbonate because the glasses do not have frame around the lenses only the minimal.

What do you guys think?

How about Zeiss lenses? How is it´s anti reflex protection?

Also the new non branded lenses already made a scratch because they were dropped but the old´s Essilor fell from higher positions and never made a mark??

Are you an eyecare professional John? If so we can help - if not, you should seek the advice of a dispensing optician in your area.

I am planning to open a Optics shop so i could really use the help because the first phase is studding the Optics world and see if i can understand it well.
I decided to understated the problem of the lenses of a friend of mine because he is not satisfied with them but he doesn´t thrust anymore his optics shop because he read lots of bad thing about the shop. I dont care about that i just want to approach/understand the cientific way of the lenses. I already see another friend of mine that have lenses with the same green reflection and he says that he likes them because they are clear then the previous ones´s.

John - Have a look at http://www.opticampus.com The CE articles are great and will give you an idea of the maths involved in studying opticianry, or optometry. Optometry is quite science based, health, anatomy, diagnosis, etc. where opticianry is more art and science combined - fashion focused, sales focused, understand physics of lens designs, and then a bit of psychology thrown on top - to understand the patient.

You can also get great information from http://www.2020mag.com look at their CE section.

If you're wanting to become an optician - do you need the same qualifications as they do in the UK or is there a different sent of rules for Portugal.

BTW - do you own a vineyard and if so, are there free bottles shipped with every good reply to your posts??? (Just kidding) Port wine from Portugal .. mmmmmmmm
